Specification of Letters Patent.

Patented Sept. 19, 1905.

Application filed May 13, 1905- Serial No. 260.277.

To all whom it may concern:

Be it known that I, AUGUSTUS C. DUDLEY, a citizen of the United States, and a resident of Kansas City, in the county of Jackson and State of Missouri, have invented a new and Improved Lantern, of which the following is a full, clear, and exact description.

This invention relates particularly to improvements in signal-lanterns for railway use, the object being to provide an ordinary whiteglobe lantern with an auxiliary colored signal-globe so arranged as to be readily adjusted around a lamp-flame when required for signal purposes or raised above the flame, so that the white light will show, thus practically forming two lanterns in one structure.

Other objects of the invention will appear in the general description.

I will describe a lantern embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional elevation of a lantern embodying my invention. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is an elevation of the lamp removed from the outer globe. Fig. 4 is a section on the line 4 4 of Fig. 1. Fig. 5 is a section on the line 5 5 of Fig. 2; and Fig. 6 is a fragmentary detail ofthe oil-cup, showing an opening to 'receive one of the fastening-lugs of the lantern.

Referring to the drawings, 5 designates an ordinary white globe, and 6 the lamp arranged in the base of the lantern. The frame for the auxiliary or colored signal-globe comprises a lower ring 7 and an upper ring 8, which are connected one with the other diametrically opposite by standards 9. An auxiliary globe 10 is shown as cylindrical and of course open at the top and bottom. At opposite sides of the frame are tubes 11 12, and passing through the tube 12 is a rod 13, While a rod 14 passes into the tube 12. The lower portion of the rod 13 is reduced in diameter and is movable vertically in a tubular guide 15, extended upward through the body of the lamp 6. This reduced portion of the rod 13 has a swinging extension 16, which passes through an opening in the bottom of the lamp and also through an opening in the drip-cup. Surrounding the reduced portion of the rod 13 within the tubular guide 15 is a coiled spring 17, which serves to move the frame and colored globe upward, as will hereinafter appear. The rod 14 is movable in a guidetube 18, secured in the lamp-body and open at the top. The globe 10 is removably held in place by means of locking-plates 19, mounted to swing on headed studs 20 at the upper ends of the tubes 11 and 12, and these looking-plates 19 are pressed yieldingly down ward against the upper edge of the globe 10 by means of springs 21, which engage at their lower ends with said plates and at the upper ends with the heads of the lugs 20.

The lamp 6 is held in the base portion of the lantern by the usual meansthat is, the said base is provided with a lug 22 for engaging in a slot 23, formed in the vertical wall of the drip-cup 24, and at the opposite side is a lug 25 for engaging in a perforation in the spring yielding clip 26.

The operation of the device is as follows: Assuming the colored globe to be red and it is desired to show the same illuminated, the frame carrying said globe is to be drawn downward by pulling upon the ring secured to the lower end of the rod-section 16. As this swinging section 16 passes to the under side of the drip-cup, the said section is to be turned to substantially horizontal position or against the under side of the drip-cup, thus locking the auxiliary globe in its lowered position around the lamp-frame, as indicated in Fig. 3. It will be noted that the swinging section 16 engages with the bottom of the dripcup at opposite sides of the opening in the bottom of said drip-cup, thus locking the parts.

When the signal or colored globe is not desired for use, the frame carrying the globe is to be drawn slightly downward until the section 16 of the rod 13 may be swung into alinement with the main portion of the rod. Then the spring 17 will automatically move the frame carrying the auxiliary globe upward.

Having thus described my invention, Iclaim as new and desire to secure by Letters Patent 1. In alantern, the combination with a main globe and a lamp in the lantern, of a frame having vertical movement over the lamp, an auxiliary globe carried in said frame, springpressed plates for engaging the upper portion of the globe and a spring for moving said frame with the auxiliary globe upward.

2. In alantern, the combination with a main globe and a lamp in the lantern, of guide-tubes extended upward through the body of the lamp, a frame arranged over the lamp, rods IO iary globe-carrying frame having Vertical movement over the lamp, the said frame consisting of lower and upper ring-like members,

uprights connecting the ring-like members, and spring-pressed plates mounted to swing at the upper portion of the frame for engaging with the upper edge of the auxiliary globe.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

AUGUSTUS C. DUDLEY.
